Description
Summary:A physical and mathematical model of spark ignition and combustion of boron powder suspension in a propane-air mixture is presented. Dependences of the critical energy of spark ignition on the radius and mass concentration of particles and propane content in the boron gas suspension are obtained. Dependences between the steady flame propagation velocity in a boron powder suspension in a propane-air mixture on particle radius and particle mass concentration are obtained, and the propane content in a boron gas suspension is determined. Quantitative correspondence of the computational and theoretical values of the flame propagation velocity in a boron powder suspension in a propane-air mixture with known experimental data has been obtained.
